Discussions:

C: Using evaluation methodology is a proven process taken by other TGs.

C: It’s possible to combine functional requirement document and usage model document.

R: many of the documents can be combined and still make sense, the real question is whether the group is interested in putting the time to develop requirements and relevant content, or is it such that the content is clear enough without the need for the time overhead and effort associated with these.

Straw Poll:

For the development of TGazamendment we prefer the following documents to be used:

D1: Usage model, D2: Functional requirement, D3: Specification framework, D4: Channel model?

For D1: Yes 23, No 0, Abs 0; For D2: Yes 21, No 0, Abs 0; For D3: Yes 21, No 0, Abs 3;

  1. Jonathan Segev (Intel Corporation) presented liaison from ATIS standard on emergency location (11-15/0992).

Discussion:

C: In the proposed architecture the WLAN presumably extends to AP STA only and not the non AP STA which is included in the UE. This is different than the 802.11 standard view.

C: The document does not include UE definition, my understanding is that other elements such as mobile OS, cellular baseband and protocol stack, GNSS components are all part of that UE.

C: 802.11 location support is already part of 802.11-2012 (11v, 11k) further complemented by REVmc FTM.

C: E911 services are both network and device centric usages, the response should indicate whether both are supported in the relevant 802.11 specifications.

C: WLAN talking to UE could be an issue to support the architecture. It is recommended to present WLAN location architecture to ATIS.

TGazworked on the response to ATIS ELOC TF.

Motion (#6)

To approve document “11-15/1172r0-00-Response to ATIS ELOC liaison communication.docx”as the IEEE 802.11 response to ATIS ELOC TF request and grant the 802.11 chair editorial license.
